I was going to make it by having a UIImage on the view then assigning the banner image. I would then add a touch gesture so the user could click it and go to another view in my app. I Know That I can do this on one view quite easily but I want this to be on most views in the app. Whats the best way for adding the banner to more than one view with out writing the same code more that once?

Try creating a parent class from UIView where you do all the display and handling of the banner using your UIImageView and gesture recognizers. Then whichever views need this functionality, derive them from this parent class, and override default handling in method so that you can customize the behavior in your child class.

What everyone else has said is the best way. If you need custom functionality, subclassing is probably the way to go.

I just wanted to add one pedantic thing. Its important to remember that a UIImage is not a view. There has never been a UIImage on the screen, ever. A UIImage is a model object. It is just a collection of data. A UIImageView is a view object and as such, a UIImageView can display itself on the screen.

This might seem overly pedantic and nitpicky, but its important to have these things sorted out in our heads in order to effectively use MVC (model, view, controller)
